` "Beitknown` hat we; JOHN AMERICUS FAN' snAwE, of` Tottenhamyin thecounty of Mide dlesex-,iin` that `part of; the United Kingdom of GreatBrilainfand =Ireland known as England,

o engineer, and JAMES ARCHIBALD JAQUEs, of

` the same'fplace, chemist, `have invented "new l Improvements lin i theConstruction of. 'Steame Generators, (for :which Letters `Patent weregranted inyGreatBritain bearingfdate the 31st `dayof October, 1861,) l`and we do .hereby del clare that "the following is a full and exact de-`scr-iption of our saidfinvention.A o Ofvur" invention of improvementsin 1 the conl o o strnctionof steam-generators has for its object to4construet steamegeneratcrsin., such a manner thatthey `,may be Lmademuchstronger: than heretofore. hewater-spaces andilues orlsmoke-passagre also so arranged and combined that uch `as possible of the caloric`contained he' heated gases-that are `evolvedfrom th gnited fuel may beabsorbed by thewater coutainedpin the generator, so' that. aconsiderable economy of fuel may be effected.` J

" To this end thelgenerator is subdivided into several narrowwaterLcompartments, between.

which fines of a convolute orserpentine form e are arranged, lsothat theheat may be absorbed l from `the gases as theypass from the lire-placethrough .the convolnte or serpentine ilues to the chimney. l 'lhelliues`or passages for the heated gases maybe formedof narrow widths ofwroughtlorplateiron rolled up into a con- 4volute, or serpentine form,and when they are placed between thenarrow water-spaces (of which theremaybe any convenient number,

- according f tothe size or capacity whichit is desired to give "to theboiler) the narrow waterspaces, with `the `Ieonvolute or serpentine oiinesor -passages between them, ,are rmly bolted together, `oraresecured in a suitable framing; or, `il' preferred, the plates a maybeo bulgedoutor corrugated at certain parts, so `that when `broughttogether they will form l passages orjspaces along which thegases from`the fire-place maybe conducted. By this means `algreatlyincreased `lenth of line is obtained water to absorbtheheat 'froml the gases vas theypass from the fire t `the chimney. The fur- .TED

In the accompanying drawings, Figure 1,

Sheet I, is an end elevation of one of our improved steam generators.Fig. 2 isl a side elevationfof the same. AFig. 3, `Sheet 1I, is alongitudinal vertical section` of, the boiler. Fig. 4 isatransve'rsevertical section in the line 1 2 of Fig. 3, and Fig. 5 is a similar Viewtaken inithe line 3 4 of Fig. 3. v

o The 'boiler is composed of a series of narrow compartments, A A A A,which are the water-spaces. These compartmentsare composed of sideplates, f1/a a a 'a' a', and narrow rings b b b, which pass all roundthe compartments A, and are secured to the side plates, c a a'n, 'nymeans of angle-iron c c and rivets, as seen in Figs. 3 and 5. 4

The side plates, ct a, are ,corrugated at the lower part at a a', sothatwhen two compartments A A are brought together, as shown inthedrawings, the corrugated parts will form a curved convolute orserpentine iiue or passage for the gases froml the furnace or rire-`place B to thecommon exit-flue C.. A central hole, D,is made through allthe compartments, and through this hole is passed a solid or tubulartiered, d, provided with screw-nuts at one or'both ends, so that byscrewing up the nuts on the tie-rod all the compartments A may be heldltightly together.- The external spaces betweentheliolesor openings inthe comparti .The narrow watery ments are lled up'by hollow rings e e,through which the tie-rod d passes, and the internal spaces round thetie-ro d are made good by other rings f f, which areperforated allround, so as to allow the-water from one compart ment A to ilow into thenext, and so on throughout the series, in order that a propercirculation of water may be kept up through out the boiler.

If desired, the tie-rod d may be made tubular and branch tubes therefrommay be made to dip nearly to the bottom of each waterspace, so as tokeep up a circulation of water in the lower parts of the compartments,and prevent the accumulation of sediment or solid matters which wouldotherwise form an iuerustation in the boiler, or, if desired, the boilermay be supplied with water through the tubu 'lar tie-rod.

The upper parts of the compartments A A, together with the interveningspaces E between the several compartments, are made to form one largeVwaterspace from end to end ofthe boiler, and common to all thecompartments A by forming large circular openings in the sides of thelatter, as shown in the sectional view, Figs. 4 and 5. The interveningspaces E between the compartments A are closed by 4means of wronght-ironrings h h, which'are secured to the sides a a of the water-spaces bymeans of angleirou and rivets and bolts i i,

instead of allowing the heated gases from the furnace to pass directinto the chimney, and from thence into the atmosphere, we conduct themalong a return flue, which is placed in the steam-space above theboiler, in order to dry and superheat `the steam before it is aliowed topass to the working-cylinder. When no additional steamchamber isemployed, a

Steampipe, k, provided with suitable stop-l cocks, is adapted to the endplate of the boiler, as seen iu Figs. 3, 4, and 5. A safety-valve, l, isadapted to a steam-pipe fixed iu the end plate at the opposite end ofthe boiler.

When it is desiredto obtain access to the interior of the boiler, thetie-rod j may be loosened and the man`hole cover on one of the endplates removed. A man can then get inside and can remove the nuts of anyof the compartments A, so that the latter may be taken out, if required,after removing the tie= rods d and j, i

What we claim as our invention, and desire to secure by Letters Patentof the United States of America, isf--` The constructing of steamboilerswith a series of distinct narrow water, spaces or compartments combinedtogether'side byside and having provided between them `convolute,curved, or serpentine lines or tire and gas passages, substantially asherein speciiied.

In witness whereof we, the said JOHN AMERIoUs FANSHAWE and JAMES Ancnr.
